Charli XCX performed on the 'Late Show with David Letterman' last night - and it wasn't a performance of 'Boom Clap' OR 'Break The Rules'!

Instead she performed the closing track from her sophomore album 'Sucker', 'Need Ur Love' - the song that was produced with Rostam Batmanglij of Vampire Weekend. Rostam also performed with Charli - she stood on top of the piano while he played it.

This is one of my favourite tracks from 'Sucker', and I'm so glad it was performed live!
